Version Found: v1.03a
Version Resolved and other Known Issues: see (Xilinx Answer 44969)
If I attempt to perform a write (Memory Write) to address 0x0000_0000, the request is mistaken as an MSI request. The core should never look for a MSI request when in Endpoint configuration.
This is a known issue that is scheduled to be fixed in theISE 14.3release of the core.
To work around the problem, you can add the following expression into the axi_enhanced_rx_demux module where pkt_addr == msi_address && pkt_typr[4] == 1'b 0:
&& C_ROOT_PORT == TRUE
Modified code:
if(pkt_addr == msi_address && pkt_typr[4] == 1'b 0 && C_ROOT_PORT == TRUE) begin
